There is a heap-based buffer over-read in the Image::printIFDStructure function in image.cpp in Exiv2 0.26. A Crafted input will lead to a remote denial of service attack.
There is a Segmentation fault in the XmpParser::terminate() function in Exiv2 0.26, related to an exit call. A Crafted input will lead to a remote denial of service attack.
There is a heap-based buffer overflow in the Image::printIFDStructure function of image.cpp in Exiv2 0.26. A Crafted input will lead to a remote denial of service attack.
There is a heap-based buffer overflow in basicio.cpp of Exiv2 0.26. The vulnerability causes an out-of-bounds write in Exiv2::Image::printIFDStructure(), which may lead to remote denial of service or possibly unspecified other impact.
There is an infinite loop in the Exiv2::Image::printIFDStructure function of image.cpp in Exiv2 0.26. A crafted input will lead to a remote denial of service attack.
A flaw was found in Exiv2 0.26. The samples/geotag.cpp in the example code misuses the realpath function on POSIX platforms (other than Apple platforms) where glibc is not used, possibly leading to a buffer overflow.
